The Dreaded CEL
Ho hum,
So on friday night my car was louder than usual and I had a look to see that the manifold had come away from the cat replacement pipe. I need a MOT so i took the car to a local garage and had my CAT put back in. The car was running perfecty until this morning. It had been raining heavily all night and when i started the car the CEL came on. The car is running very badly, lumpy idle, 'rooing like a mofo etc.
Can anyone suggest the possible causes/resolutions ?

So have you now got an OEM cat in, with the OEM lambda in it now, and you got a CEL?
Have you left the anti fowler plug in?
The symptoms you describe are that of a damaged priamry lambda - the one in the manifold. Hopefully they haven't twatted it.
I would reset the ECU as it may have become confused due to the air leak.

could be the idle control valve.
had this after engine transplant.
starts ok then but when trying to drive slowly the bleddy thing jumps around like an over enthuiastic puppy.
and when idle revs up and down like a whores draws.
found that switching off and restarting stopped it which at least makes the car drivable but ultimately if it this the icv it needs replacing
